Recipe Tips

Preparation

Place sliced onion in a strainer and rinse under cold water for 20 seconds; drain. Transfer onion to a large bowl; add vinegar and toss to coat. Set aside.

Meanwhile, boil potatoes in a medium pot of lightly salted water until tender, about 45 minutes. Drain. Let cool slightly. Using a kitchen towel, rub skins off potatoes. Cut potatoes into 3/4" pieces and transfer to a medium bowl; drizzle wine over. Season with salt and pepper and gently toss to combine; set aside.

Add shrimp, tomatoes, and oil to bowl with onions. Season with salt and pepper and toss gently to incorporate. Let sit for 5 minutes until flavors meld. Add basil, toss gently, and serve.
